Soil fractionation offers one way to try to tease out soil carbon dynamics beyond bulk. Using a linear-mixed effects model and large soil carbon database ( #ISRaD ) Heckman et al 2022 https://doi.org/10.1111/gcb.16023 found that depth was critical in explaining soil carbon stocks and persistence. Many traditional ClORPT variables were also explanatory, except for NPP, though their effects of different fractions differed. #SoilCarbon #DataCollection #Reanalysis #sciLit
